Abstract

The periodogram analysis of theV observations of the δ Scuti star HR 1225 has been carried out. Two frequencies of 6.415 cd (P 0=0 d. 1558) and 8.418 cd (P 1=0 d. 1188) have been determined. The period ratio ofP 1/P 0=0.762 indicates radial pulsation. The absolute magnitude, effective temperature and mass of the star are derived to be 1 m. 05, 7600 K and 1.9M ⊙, respectively.
